\ Application filedJanuary 28, 1913. Serial No. 744,686.

Mol ne, in the county of,.Rock Island and State of Illinois, have invented certain new and'usef I pr'oveinentsin Blow-s ot which the'following" is a'specification, reference be; ing ,ha d therein to the accompanying drawing for the component parts of'a plbw,- .and.th objectthereqf is to provide a plow bottom in which the point or share niay bQ QXP editiously' attached: to or. detached from the other parts of the plow body, I

Inthe' aecqin anyingjd'rawings I have shown'piie' einbo iinent of my invention. It will, bel understood, however, that the right is reserved to'effeet' such modifieations and variations of parts, and structural details, as may come :fairly Within the scope of the appended claims, I I v Oi he d awings Figu 'r e]l is a perspecfti'veyiew of a plow embodying my invention. Fig'i 2 is va bottom perspective view of a plow showing .the fastening means in an: active position. Fig; is asiinilar view illustrating the fastening means in act ve position.

Referring nioreparticularly to the draw ings, 1 designates the plow point. or share; 2 the moldboardg 3 the landside; andfi the frog to whitilrthe other, parts are attached by neansof bolts or rivets 5, and a fastening deyice which will be hereinafter describedlfl i 4 Preferably,'th'e fior'ward, extremity of. the frog 4 isprovided with, a circular opening- 5 adapted .to, receive the correspondm ly shaped body portion 6.0 a Washer 7L his washer is formed with an" an n ular flange as 8, which is designed to rest upon the. falce of the ,frog' immediately adjacent the body portion of he washer teammates at a point short of t e depth or transverse exof tii'e p'low share, lIuStriTt'ingthe fastening said openings, while theinner, face, of the;

tent of the opening 5*, as will be found upon inspection of Fig. 5.

D 'sposed eccentrically and at substantially right angles with respect to the body portion of the washer, is a head 9 in the form of a nut, having a bore, as 10, extending centrally therethrougli, as well as through said body portion, and adapted, for registration with the opening 11 in the plow share 1. The bore 10 and opening 11 are employed in conjunctionwith a clampbolt 19 and nut 13 for, the purpose of assembling the washer in proper relation to the plow share and frog. In use the plow share 1 and frog a are arranged'in superposed relation, with the opening 11 of the plow share adjacent the wall of the opening The bolt 12 is then thrust through both bolt openings, and tlie washer 7 is passed over the protrudingektreinity of the bolt until the annular flange 8 seats against the frog, whereupon the nut 13 is screwed upon the free end of the bolt until it barely engages the head. This engageinent of the nut and head is justsufficient to retain the body portion of the washer in the opening an at t-liesame time perinit itlbeing rotated upon the bolt With respect to said opening. The position of the washer is clearly shown in Fig. 2, wherein it will be seen that the bolt which constitutesthe axis of the washer is located in proximity to the adjacent edge of the .frog' 4,Wl 1iltl l6 plow share is slightly removed from the landside 3and moldboard 2, Upon rotating the washer 7 toward the right less thana quarter turn the bolt, owing to its eccentric disposition, will constrain the share toward the inoldboard but away from the landside. Further rotation of the washer still shifts the share toward the landside and also toward the inoldboard, and it is while the bolt is substantially in this quarter that the share is positioned and forced tightLy against both the moldboard and laiidside, as illustrated in Fig.3. The share is held in this position by tightening the nut on the bolt, and in thisconnection it will be pointed out that the nutis caused to engage the head 9 of thewasher, which in turn simultaneously forces the annular flange 8 against the frog, and draws in the opposite direction upon the head of the clamp bolt. As herein described, the body portion 6 of the washer as justably engaging the walls of a circular is of less extent than the depth of the opening 5, and it follows that when the nut is tightened upon the bolt the confronting faces of the share and frog will frictionally engage each other, so as to constitute a reliable clamping action, which will positively prevent displacement of the parts.

lVhen it is desired to detach the share, the bolt is loosened, the washer rota-ted toward the left until it reaches the position shown in Fig. 2. Then the nut is removed from the bolt, and the share is free.

It will thus be seen that I have devised fastening means, extremely simple in construction, which will permit of the plow share being quickly attached to and detached from the other parts comprising a plow bottom, thereby greatly facilitating the operation of removing the share for the purpose of sharpening, making repairs, or substituting an entirely new share.

What is claimed, is

1. The combination with a plow body,

comprising a moldboard, a landside and a connecting frog, of a detachable share engaging the frog and having a part alining with the moldboard and a part alining with the landside, and an eccentric member fiX edly pivoted directly to the transverse blade of the share at the lower face thereof, the said eccentric member having engagement with the frog and serving when turned to slide the share along the frog.

2.
